The Silicon Labs C8051F502-IM is a high-speed 8051 microcontroller in a 32-VFQFN package. It operates from 1.8V to 5.25V, runs at 50MHz, and includes 64KB flash and 4.25K RAM. With an internal temperature sensor, PWM, and WDT, it is designed for robust industrial and automotive applications.
- Wide voltage range: 1.8V to 5.25V simplifies power supply design.
- High temperature tolerance: -40°C to 125°C for extreme environments.
- Integrated temp sensor: Eliminates external sensor for thermal monitoring.
- Compact 32-VFQFN: Small footprint with exposed pad for thermal dissipation.
Automotive Sensor Interfaces
With 1.8V to 5.25V operation and 125°C rating, it directly interfaces with 5V sensors in engine bays.
Industrial Process Control
The 50MHz 8051 core with PWM outputs can drive valves and pumps, while the WDT ensures continuous operation.
Battery-Powered IoT Nodes
